I took some pvc pipe from Lowe's, drilled a few holes to add some standard air line connectors, a filler cap, and a Schrader valve for water pressure, mounted it to the top of my roof rack for a solar shower, holds about three gallons! Took a few brass fittings from Lowe's and made a stepdown connector that a standard garden hose nozzle fits on... Works great! I also have a privacy shower tent I picked up on a road trip on the east coast... Happy to send/post pics to anyone interested.
